I have exhaust manifolds DOAE 9430-G and DOAE 9431 G from a 1970 351 4v mustang. Will they also fit a 71 351 4v mach ?

Pretty sure the passenger side will fit but the driver is different. Not sure if the outlet will be in a usable spot.

Oh well, I wanted to stay with stock type exhaust, but I'll go ahead and put long tube Hookers on it. Thanks for the response.

Passenger side is the same, driver's side manifold is different. I believe it was needed to clear the relocated clutch Z bar in the 71-73s. If you are running an automatic, you might be okay, just need to run a 70 H-pipe.
